Abstract (en)
[origin: WO2010036214A1] This invention is related to the preparation processes and the products of polymeric composites containing antibacterial properties. The composites were prepared from the medical grade polyurethanes and silver ion containing zeolites which the synthesis procedures of both are also included in this invention. Zeolite crystals were prepared in various forms as micro and nano particules and at different SiO2/Al2O3 ratios. Antibacterial properties were included with addition of silver ions into zeolite particules. Medical grade polyurethanes were synthesized from their components in the presence of no other additives in various forms as films sponges or fibers. Composites were formed with combination of these two components. The prepared antibacterial composite materials can be applied in textiles, paint industry, coating materials for metals ceramics or wood, public toilets, keyboards, paper industry, household hygene items, cosmetics, hospital beds and floors, etc.
